Editorial Note: New Categories

For some reason I got it in my head that it would be a good idea to go back and redo my categories on this blog. The categories before yesterday were default plus a handful that I added over time. You can see the new list of categories at left, which are a far better fit. I hope this will be useful to readers interesting in learning more about some of the topics covered -- especially symmetry breaking, synchronization, flow, and systems theory.
